BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to a smoking device.

2. Related Background Art

Water pipes or Hookahs or more recently bongs have existed for a verylong time. The advantages of using water to cool and perhaps flavor orotherwise condition the smoke before inhalation are well known. Therehave been many variations of adapters and connectors for using ordinarydrink bottles as integral parts of these smoking devices. There arehowever still some disadvantages of the adaptations known in the art.The attachment of a glass or metal pipe bowl that is known to get hotduring use to a plastic bottle requires some care with respect to heattransfer. In some variations of use it is important to also be able toeasily attach and remove the pipe bowl during use. This requires anattachment that is relatively airtight but also allows easydisconnection and reconnection and at the same time allows the user tohandle the pipe bowl containing hot embers without harm. A popularvariation of a pipe for smoking is known as the gravity pipe. In thiscase a bottle with the bottom cut off and with an attached pipe bowlattached to the mouth of the bottle is partially immersed in a waterreservoir. Raising the bottle with the bowl attached draws air throughthe pipe bowl and air mixed with smoke into the bottle. The pipe bowl isthen removed and the bottle when lowered emits smoke through the mouthof the bottle. The smoker may then inhale the smoke emitted from thebottle without the need to suck on a pipe. This gravity pipe device isespecially dependent upon a means to easily attach and remove a smokingdevice from the mouth of a bottle.

DISCLOSURE OF THE INVENTION

The present invention relates to a smoking device and adaptersassociated with use of the device. One embodiment of the invention is asmoking device comprised of a pipe bowl device comprised of a bowl forcontaining material to be smoked and a fitting at a second end oppositethe bowl. The pipe bowl device is constructed of material that canwithstand the heat of burning embers without melting or decomposition.Exemplary materials include glass and metal. The fitting is sized to fitan adapter that is used to create an airtight seal between the pipe bowldevice and the mouth of a bottle. In one embodiment the adapter fits toa hole drilled through the cap of the bottle. The cap screwed in placeon the bottle. In another embodiment the adapter is sized such that itfits under the cap of the bottle and the cap when screwed onto thebottle fit with the adapter ensures an airtight seal between the adapterand the bottle. In yet another embodiment the adapter is designed suchthat as a single integrated unit includes the heretofore two parts ofthe bottle cap and the adapter. Typically the bottles are large twoliter plastic bottles such as those used for soft drinks The adapter isconstructed such that it creates an air tight seal while at the sametime permits easy attachment and removal of the pipe bowl device. Anexemplary fitting would be ground glass fittings where the adaptercomprises a female fitting and the fitting on the pipe bowl devicecomprises a male fitting also made of ground glass. The bottom of thebottle is cut away to produce an approximately two-liter cylinder with amouth with the fittings at one end and an approximately four-inchopening at the other. The device further includes a reservoir that issufficiently large to contain substantially the entire volume of thebottle. The reservoir is filled with water.

In use, the bottle is lowered into the reservoir with the mouth of thebottle containing the adapter and pipe bowl device above the waterlevel. The bowl of the pipe bowl device is filed with the material thatis to be smoked, typically tobacco. The material to be smoked is litfrom a flame and the bottle is slowly lifted from the water. The resultof the lifting motion is to draw air through the bowl device andsubstantially fill the bottle volume above the water with smoke from theburning of the material to be smoked contained in the pipe bowl device.The bottle is lifted only so far as to fill the bottle with smokewithout lifting the open end of the bottle above the water level in thereservoir. An airtight seal is maintained at the open bottom of thebottle between the bottle and the water in the reservoir. Once thebottle is nearly, but not completely, lifted from the reservoir, thelifting motion is stopped and the pipe bowl device is removed from theadapter opening the mouth of the bottle to the air. The bottle is thenlowered back into the reservoir. The lowering action forces the smokefrom the interior of the bottle out through the adapter and mouth of thebottle. The smoke is inhaled by the user.

In another embodiment the adapter and the pipe bowl device are replacedby a single integrated unit. The single integrated unit combines a pipebowl with the adapter fitting such that a single unit is attached to thebottle during use. And in yet another embodiment the single integratedunit is designed such that its shape replicates that of the combinedbottle cap and adapter.

MODES FOR CARRYING OUT THE INVENTION

Referring now to FIG. 1, a pipe bowl device 101 is seen attached to abottle 102 that is partially immersed in water 109 contained in areservoir 103. The bottom of the bottle 104 is cut away. The pipe bowldevice is attached to the bottle through use of an adapter 107 and fitsthrough a hole in the bottle cap 108. The pipe bowl device includes abowl 106 at the top end for receiving the material to be smoked. Thepipe bowl device otherwise is comprised of a hollow cylinder 111.Exemplary materials used for the pipe bowl device 101 are glass, metal,ceramic or any material typically used or capable of withstanding thetemperatures encountered in a typical smoking pipe. The adapter 107likewise can be made of any material that can withstand the temperaturesencountered and can be machined to create an air tight fit of aninserted pipe bowl device. Typical materials are glass, metal andplastic. In a preferred embodiment the adapter is made of glass. Anexemplary and preferred embodiment bottle 102 is a two-liter plasticsoft drink bottle. Other materials such as glass are also used. TheBottle 102 could also be a cylinder constructed to have an open bottomand a restricted opening at the top to accept the adapter 107 and neednot necessarily be a bottle.

The method of using the device, again referring to FIG. 1, compriseslowering the bottle 102 into the water 109 contained in the reservoir103. The pipe bowl device 101 is removed from the adapter 107 whilelowering the bottle 102 into the reservoir 103. The bottle is loweredonly so far such that the cap 108 is still held above the water line105. Once lowered the pipe bowl device is attached through the adapterfitting 107. The pipe bowl 106 is filled with material to be smoked andthe material is lit with a flame. In some case the material to be smokedis lit while simultaneously slowing raising the bottle 102 from thereservoir 103. The bottle is raised only so far as to maintain thebottom of the bottle 104 below the water line 105. Raising the bottlecreates a partial vacuum within the bottle thus drawing air through thepipe bowl 106 and smoke from the now lit smoking material into theinterior of the bottle. Once fully raised, such that the bottom of thebottle 104 is still below the waterline 105. The pipe bowl device isremoved from the adapter 107 and the bottle 102 is lowered back into thereservoir. Lowering the bottles forces the smoke held within the bottleout through the mouth of the bottle. The emitted smoke is inhaled by theuser. Exemplary materials for smoking include a wide variety oftobaccos. The device could further be used for the administration ofmedicants that are capable of being vaporized in much the same fashionas tobacco is used during smoking.

Referring now to FIG. 2 a detailed view of many of the embodiments ofFIG. 1 is provided. The pipe bowl device 101 is seen to be comprised ofa bowl 106 in which the material to be smoked is contained. The deviceincludes a bowl 111 that will contain the material while still allowingpassage of air. Nonlimiting exemplary constructions include a solid bowlwith a small hole in the bottom or side as typically is used inconstruction of smoking pipes, a bowl with a wire screen bottom, and aglass bowl with a fitted glass bottom. The pipe bowl device 101 isfurther comprised of a fitting 201 located at the lower extremity or endopposite the bowl 106. In a preferred embodiment the fitting 201 is atapered fitting that is sized to fit the interior 202 of the adapter 107and form a substantially air tight seal with the adapter. The pipe bowldevice is seen to be further comprised of a hollow cylinder 112connecting the two ends of the device. The adapter 107 is comprised of acylinder comprising an outer surface 203 an inner surface 202 and a lip204. The inner surface 202 is of a size and surface finish to mate withthe corresponding surface 201 of the pipe bowl device. In a preferredembodiment the pipe bowl device 101 and the adapter 107 are composed ofglass and the mating surfaces 201 and 202 are ground glass fittings thatenable an air tight fit while still be easily connected and disconnectedfrom one another as required during use of the device as alreadydiscussed. The outer surface and overall size of the adapter 107 areselected or constructed such that the adapter will fit through the hole205 in the cap 108 on the bottle 102. The lip 204 on the adapter issized slightly larger than the hole 205 to prevent the adapter frompassing completely through the hole and provide a mating surface withthe bottle cap for attachment with an adhesive (not shown). The cap 108includes threads that mesh with threads 110 on the mouth of the bottlesuch that the cap may be screwed onto the bottle and create asubstantially air tight seal between the cap and the bottle. In apreferred embodiment the adapter is made of glass and the outer surface203 is tapered such that when inserted it creates a substantially airtight seal in the hole 205.

Another embodiment further includes an elastomeric washer 208 that ispositioned between the cap 108 and the lip of the bottle 206 such thatwhen the cap is screwed onto the bottle the washer 208 is compressed toform a substantially air tight seal between the cap and the bottle.

In another embodiment, not shown, the adapter and the outer surface areconstructed and sized such that when inserted the adapter forms asubstantially air tight seal with the inner surface of the lip of thebottle 206 itself and the cap 108 is not used in the device.

In another embodiment shown in FIGS. 3A and 3B, the cap and adapter ofthe previously discussed embodiments is replaced with an integrated unit301. The integrated unit is comprised of an inner cylinder 302 and a cap304. The cap and the cylinder are constructed to create a substantiallyair tight seal when mated with the mouth of the bottle 102 shown inFIGS. 1 and 2. The integrated adapter unit is further comprised of aninner surface 303 that is sized and constructed to form a substantiallyair tight seal with the surface 201 (FIG. 2) of the pipe bowl device.The outer surface 302 is sized and constructed so as to form asubstantially air tight seal with the mouth of the bottle 206 (FIG. 2).The integrated adapter is otherwise hollow 305 to allow free passage ofair and smoke between the pipe bowl device and the interior of thebottle. The integrated adapter may further include a threaded surface306 (threads not shown) to allow the device to be screwed onto thebottle. The integrated adapter is comprised of material that can eitherbe machined to form the shapes shown, such as would be the case of ametal or wood adapter. In another embodiment the adapter is molded froma high temperature plastic or ceramic material. Exemplary materialsinclude thermoset plastics and thermoplastic materials that canwithstand high temperatures such as polyimides, polyether ether ketonesand others known in the trade.

FIG. 4 shows use of the integrated adapter 301 in conjunction with apipe bowl device 101 and a bottle 102. The integrated adapter 301 fitsatop the bottle 102 such that the outer surface 302 of the adaptercylinder mates with the inner surface 206 of the mouth of the bottle. Inone embodiment the cap portion 304 is threaded on the interior withthreads sized to match the threads 110 on the mouth of the bottle. Inthis embodiment the integrated adapter is screwed onto the bottle topforming a substantially air tight seal. In another embodiment the cap304 is not threaded and a substantially airtight seal is formed form afriction fit between the tapered outer surface of the adapter 302 andthe inner surface 206 of the mouth of the bottle. Another embodimentincludes a smoking device that incorporates the integrated adapter, apipe bowl device and a bottle. The other components the same aspreviously discussed. The use of the smoking device that incorporatesthe integrated adapter is equivalent to the use already described.

In another embodiment shown in FIGS. 5A and 5B and 6, the integratedadapter 501 further includes a screen 505 that is incorporated in theinterior of the of the central cylinder 504 to create an integratedsmoking adapter. The interior 503 of the device can now be used as apipe bowl and the need for a separate pipe bowl device is eliminated.This integrated smoking adapter 501 is comprised of a cylinder 504having an interior surface 503 and an exterior surface. The device 501is further comprised of a second cylinder 502. The second cylinderincludes an interior surface 507 that may be threaded (threads notshown) to fit the mouth of a bottle as discussed below. The first andsecond cylinders 502 and 504 are concentrically arranged and joined atone end 508. The insulating gap between 509 between the cylindersprovides insulation between the inner cylinder that may become hotduring use and the outer cylinder 502 which is handled by the user. Thescreen 505 is arranged in the interior of the second cylinder 504 suchthat the cylinder 504 and the screen form a bowl for receiving materialsuch as tobacco to be smoked. In an alternate embodiment not shown thescreen may be replaced with a solid plug. In this embodiment a hole isdrilled through either the solid plug or through a sidewall of thecylinder 504. The size of the hole is selected such that it is smallenough to constrain the material to be smoked within the cylinder yetlarge enough to allow passage of air through the device when used in amanner similar to the methods already discussed and further elaboratedbelow. The integrated smoking adapter is comprised of material that caneither be machined to form the shapes shown, such as would be the caseof a metal or wood adapter. In another embodiment the adapter is moldedfrom a high temperature plastic or ceramic material. Exemplary materialsinclude thermoset plastics and thermoplastic materials that canwithstand high temperatures such as polyimides, polyether ether ketonesand others known in the trade.

FIG. 6 shows how the integrated smoking adapter 501 would fit to themouth of a bottle 102. The inner cylinder of the adapter 504 is sizedand tapered such that when inserted into the mouth of the bottle 601 theouter surface of the cylinder 506 forms a substantially air tight sealwith the inner surface 206 of the mouth of the bottle. In one embodimentthe inner surface 507 of the outer cylinder 502 is not threaded and thesubstantially airtight seal is formed by a friction fit. In an alternateembodiment the inner surface 507 of the outer cylinder 502 is threaded(threads not shown in FIG. 5B), the threads sized to fit the threads 110of the bottle wherein when attached the integrated smoking device my bescrewed onto the top of the bottle thereby forming a substantiallyairtight seal between the smoking device and the bottle.

The method of use of the integrated smoking adapter is substantially thesame as described in conjunction with the devices of FIG. 1. The bottle102 with the bottom of the bottle cut away is lowered into a reservoirsuch that the top of the bottle is out of the water, above the waterline. The inner cylinder 503 of the integrated smoking adapter is filledwith the material to be smoked, such as tobacco, and the material islighted with a match or lighter. The bottle is then raised afterlighting the smoking material, or alternatively simultaneously raisedwhile lighting the smoking material from the reservoir. Raising thebottle creates a partial vacuum in the interior of the bottle thusdrawing air through the integrated smoking device and filling theinterior of the bottle with smoke from the now lighted material withinthe bowl of the integrated smoking device. The bottle is raised out ofthe water but without raising it so far as to break the contact of thelower end of the bottle with the water surface. The integrated smokingdevice is then removed from the top of the bottle and the bottle islowered into the reservoir thereby forcing the smoke out through themouth of the bottle. The user inhales the smoke. The raising andlowering process is then repeated. With attachment of the integratedsmoking adapter once the bottle is fully lowered. The integrated smokingdevice is also referred to simply as a smoking device here and in theclaims when the distinction from other embodiments is clear.
